JBA 04-15 Nissan 5.6L VK56DE Oval Port 1-5/8in Primary Silver Ctd Cat4Ward Header

Starting with 3/8" thick machined flanges and oversized exhaust ports, these JBA Cat4Ward headers are built to handle the demands of your 2004-2015 Nissan TITAN, Armada, or Infiniti QX56. They are designed to be a significant upgrade over the restrictive stock exhaust manifolds, aiming to increase both the power and efficiency of your 5.6L VK56DE engine. The stainless steel tubing is mandrel bent for smooth airflow, and the proprietary JBA Firecone collector uses race-proven technology to maximize power and torque gains where you need them most – in the everyday driving RPM range.

Constructed from durable stainless steel, these headers are made to endure the rigors of daily driving, towing, or even racing. The extra thick collector domes add to their robust build. For a professional, no-leak installation, JBA includes factory-style emission connections and high-quality hardware. This means you can expect a solid option for improving your truck's exhaust flow and performance.
